Radio

Last week I managed to break the metal aerial on my TR6. At the weekend,
I fitted another, which seemed to go fine. I now get FM reception OK,
but I can't pick up anything on AM. I am completely baffled. Any ideas
what the problem could be? The only difference I can see is that this
aerial is longer than the old one: 4 "segments" as opposed to 3.
 
Thanks
